I'm wanting to sample a voltage at high frequency (ideally 2kHz or so). With a simple program like below I can get to about 500Hz sampling. Are there any tricks to going beyond this? I did see burst mode, but I need uninterrupted continuous recording if possible which may not be possible?
Just getting in the order of a few kHz would be ideal. I've got CR6 and CR1000X loggers here for testing.
'Main Program BeginProg Scan (2,mSec,0,0) VoltSe(my_val,1,mV200,U1,False,50,15000,1,0) CallTable Test NextScan EndProg
Thanks in advance!
The fastest you can go uninterrupted on the CR6 or CR1000X is 1kHz. You would need to further increase the fNotch parameter to get that fast.
Ah perfect that gets me up to 1kHz. Is there a way to concurrently measure multiple channels at this rate? It seems for each VoltSe measurement I have to add 1ms to the scan time.
Eg. This will complain and not complile
BeginProg Scan (1,mSec,0,0) VoltSe(my_val1,1,mV5000,U1,False,20,100000,1,0) VoltSe(my_val2,1,mV5000,U2,False,20,100000,1,0) CallTable Test NextScan EndProg
